Conversion of different model animals based on BSA (PMID: 27057123)
Species Mouse Rat Rabbit Guinea pig Hamster Dog
Weight (kg) 0.02 0.15 1.8 0.4 0.08 10
Body Surface Area (m2) 0.007 0.025 0.15 0.05 0.02 0.5
Km factor 3 6 12 8 5 20
Animal A (mg/kg) = Animal B (mg/kg) multiplied by  Animal B Km
Animal A Km

For example, to modify the dose of Compound A used for a mouse (20 mg/kg) to a dose based on the BSA for a rat, multiply 20 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for Compound A of 10 mg/kg.

TH-Z145

TH-Z145 is a lipophilic GGPPS inhibitor (GGPPS IC50 = 210 nM). TH-Z145 is a very lipophilic bisphosphonate that lacks the cationic center essential for FPPS inhibition and is thus a specific GGPPS inhibitor (FPPS IC50 >30 mM). TH-Z145 exhibited strong prophylactic effects in a pathogenic influenza model.

TH-Z93

TH-Z93, a lipophilic bisphosphonate, is an FPPS inhibitor (IC50 = 90 nM). TH-Z93 exhibits potent efficacy, increasing both antibody titers and avidity. TH-Z93 exhibited strong prophylactic effects in a pathogenic influenza model.
